Cascading Style Sheets were first introduced as a standard for Web browsers in 1997. CSS allows styles for a Web site to be coded in a single file rather than being spread throughout individual HTML files. One of the innovations that CSS introduced was the use of "fluid" layouts that allowed the text and graphics inside a browser to grow or shrink as the browser size was updated. However, if you find yourself with a fluid website in WordPress that you'd like to keep at a static size, this can be done by using the built-in WordPress editor.

Login to your Wordpress site by opening a browser and navigating to "http://www.yoursiteaddress.com/wp-admin." Substitute your site URL for "yoursiteaddress.com." Type in the admin name and password and login.

Click "Appearance" on the left side menu to expand it if it isn't already expanded. Select "Editor" from the bottom of the Appearance menu.

Select the theme that you would like to remove the fluid CSS properties from in the drop-down menu on the right side of the screen.

Look for the "style.css" file listed on the right of the screen. You may need to scroll down if your theme has a large number of files. Click on "style.css" to open it up in the editor window.

Look through the source code in the style.css window for the sections of the page that you wish to change. Most themes will have the page divided up into content and sidebar sections. For example, a content section that is to take up 65 percent of the browser space will be listed as follows: #content { width: 65%; }

Delete the percentage figure and replace it with a pixel definition. For example, to keep the content portion of your page at 700 pixels, change the code so it reads: #content { width: 700px; }
